Note: upstream qemu got device_add and device_del monitor commands 
meanwhile which can be used to hotplug devices.

device_add accepts the same syntax the -device command line switch expects.

device_del expectes an id.

For libvirt it probably makes sense to start supporting this when 
switching over to -device (probably for qemu 0.12+).
